Everyone was busy until late that night, and it was not until midnight that they were able to take a rest.
Chen Fei was too tired to care about anything else. He explained the relevant work for a while, then returned to his dormitory, fell on the bed, and fell asleep soon after.
He set an alarm clock and got up at eight o'clock the next morning.
If there was no alarm clock, he might be able to sleep until four or five o'clock in the afternoon.
He got up, washed up, drank a glass of water, and went to the command hall.
"Hello, Chief!"
"Hello, Chief!"
As soon as Chen Fei entered, many staff officers or non-commissioned officers who happened to walk nearby saluted him and said hello, and he naturally responded to them one by one.
When he reached the end, he immediately saw Lin Xiaoyan sitting in a chair, leaning against the backrest with her eyes closed.
He walked over.
Lin Xiaoyan seemed to hear his footsteps. She opened her eyes and smiled sweetly when she saw it was him: "Are you awake?"
Chen Fei saw that Lin Xiaoyan was very tired and had dark circles under her eyes. She had obviously not slept all night, so he couldn't help but wonder: "Didn't you go back and take a nap?"
"No." Lin Xiaoyan raised her hand to cover her mouth and yawned, looking extremely tired.
"You should also go back and take a rest." Chen Fei sat down next to her and said.
"I also want to have a good sleep, but the things at hand are not finished yet, so I can only hold on."
Chen Fei sighed and could only express his sympathy. The current work was complicated and complicated, but the most urgent thing was obviously Lin Xiaoyan's intelligence work. There were still shortcomings here, and they were very huge.
What happened yesterday has proved one thing, that is, the Red Army's intelligence and reconnaissance network along the defense line still has big loopholes and serious deficiencies. This is why the Blue Army's fighter jets can sneak in quietly. In a few days, the Red Army and the Blue Army will
The confrontation between the two sides is about to officially begin. If the red side's intelligence network is still like this, it will be almost impossible for the red side to win. Therefore, Lin Xiaoyan is facing considerable pressure.
It was huge, so she had to work overtime overnight.
"Old Chen, you're here just in time, can you help me take a look at this?" Lin Xiaoyan seemed to suddenly remember something, and quickly typed on the keyboard to bring up a piece of information.
She used to be called Chen Fei by the head of the department. At this time, she may be extremely tired and doesn't have so much to think about. Moreover, she is really familiar with Chen Fei. The two of them would joke with each other in private, so at this time, he naturally
He shouted after Li Yunfei, but Chen Fei felt very friendly after hearing it.
"Old Chen? This title is no longer new, you will call me like this from now on!" Chen Fei said with a smile.
Lin Xiaoyan was startled, and then felt a little embarrassed. She also realized that she had just lost her composure, but she had no intention of changing it, so she changed the subject and said, "Can you help me take a look at this?"
"What is this?" As soon as Chen Fei saw it, he was a little dazed and couldn't react. However, after taking a closer look, he quickly understood what it was. Simply put, this was a reconnaissance network diagram simulated by Lin Xiaoyan using a computer.
In other words, she used a unique algorithm to design an all-round reconnaissance network from space to the ground. On the diagram, each node represents a reconnaissance unit. These reconnaissance units are different, but they all point to the blue.
Military position.
It can be seen from Lin Xiaoyan's network map that she has great ambitions. Not only reconnaissance satellites are used, but also drones, early warning aircraft, radar stations, individual reconnaissance soldiers, etc., are all used, from the Air Force and the Army.
’s, missile brigade’s, all united together.
"Did you do it last night?" Chen Fei was very surprised.
"Pfft--" Lin Xiaoyan couldn't help but laugh, "Do you think I can do so many things in one night? This is something I have been thinking about these days, but I just made it last night."
Chen Fei nodded, stopped talking, and just looked at it seriously.
Lin Xiaoyan came up with these things after carefully studying the current red team's reconnaissance force in this area.
The current red side's reconnaissance force in this area naturally has reconnaissance satellites at the top.
In terms of reconnaissance satellites, the strongest one is naturally the United States. Not only do they have a large number of satellites, but their reconnaissance capabilities are also among the best in the world. One of them must be mentioned is "Keyhole 12". It is said that this reconnaissance satellite can clearly take pictures.
Faces on the ground, of course, this statement is too exaggerated. The resolution of the "Keyhole" series satellites is as high as 0.1 meters, which is very high, but it cannot take such clear photos at all times. It must be
It has to wait until it reaches the perigee, which is 260 kilometers above the ground. If it is at the apogee, which is 1,000 kilometers above the ground, there is nothing you can do.
However, even with a resolution of 0.1 meters, it is still impossible to directly recognize faces from space.
Because at this resolution, there are only 2 to 3 pixels available to display a human face. To truly capture a human face, the resolution must be increased by two orders of magnitude, that is, to the level of 1 mm.
However, due to the existence of the "diffraction limit", the only way to break through the resolution limit is to increase the diameter of the lens, and satellites must be launched by rockets, and the size and weight cannot be too large, so the resolution of 0.1 meters
It is basically the limit of what existing technology can achieve.
However, this also shows that the old and American reconnaissance satellites are quite powerful.
The red side's reconnaissance satellites in this area are naturally not that powerful, but they are not far behind, and they are better than the blue army. However, the blue army may receive funding from the United States, so in summary, the reconnaissance satellites alone are not enough.
In other words, the red side has no advantage.
Moreover, satellite reconnaissance is not perfect. Its advantages are obvious, but its shortcomings are also very prominent. Therefore, it needs the cooperation of other reconnaissance methods. Therefore, in addition to satellites, there must be high-altitude reconnaissance aircraft, that is, drones, and they are large-scale unmanned aerial vehicles.
machine.
In this regard, due to Chen Fei's persistence and efforts, the red side has already formed a drone brigade.
The drones equipped on the red side can mainly be used for intelligence collection, support and strike.
The maximum horizontal flight speed of this UAV is 800 kilometers per hour, the cruising speed is 500 kilometers per hour to 700 kilometers per hour, its cruising altitude is 10 kilometers, the ceiling is 20 kilometers, the maximum endurance time is 20 hours, and the maximum range
It has a range of 12,000 kilometers, a maximum climb rate of 20 meters per second, and the operating radius of the drone can reach 300 kilometers.
Therefore, the red team's UAV can be used as a long-term fixed platform in the air. And it can be operated alone or together with other manned or unmanned aircraft. At the same time, it is suitable for a variety of military tasks because it can
High-altitude reconnaissance and strike, anti-submarine warfare, and close air support missions, it can even serve as a long-range early warning detection aircraft.
The red side now barely has enough of a drone brigade, so it can have several drones flying at high altitudes at the same time. In this way, it can monitor the whole process 24 hours a day.
In this aspect, the red team is stronger than the blue team, and they can do more work on this matter.
